Patent number: 9851026Abstract: A layer for directing a hydraulic fluid includes a first fluoropolymer, a first crosslinker, and an anti-static additive. The first fluoropolymer is present in an amount greater than 60 parts by weight, the first crosslinker is present in an amount of from about 1 to about 10 parts by weight, and the anti-static additive is present in an amount of from about 0.4 to about 4 parts by weight, each based on 100 parts by weight of the layer. The layer may be included in a layered tube. In addition to the layer, the layered tube also includes an outer layer. The outer layer includes a second fluoropolymer, which is the same as or different than the first fluoropolymer. The second fluoropolymer is present in an amount greater than 60 parts by weight based on 100 parts by weight of the outer layer.Type: GrantFiled: May 12, 2014Date of Patent: December 26, 2017Assignee: EATON CORPORATIONInventors: Soumayajit Sarkar, Javed Mapkar, Edward Hummelt, Kenneth Phaneuf, Robert Michael Lefere, Joseph David Proof, Gregory James Chapman

Publication number: 20150064458Abstract: The disclosed concept relates to methods for the manufacture of molded parts having composite nanofibers deposited on a surface of the molded parts. The molded parts are manufactured by utilizing injection molding techniques. The nanofibers are capable of imparting to the molded part functionality, such as but not limited to electrical conductivity, magnetic properties, thermal conductivity, hydrophobicity and superhydrophobicity. The methods include depositing the nanofibers at least partially on an interior surface of a mold, injecting a polymer-containing composition into the mold and extracting a molded part from the mold. A surface of the molded part includes a layer or coating of nanofibers deposited thereon and/or therein. The nanofibers are transferred from the interior surface of the mold to the surface of the molded part. The mold and molded part can include three-dimensional shapes as well as two-dimensional shapes.Type: ApplicationFiled: August 28, 2013Publication date: March 5, 2015Applicant: EATON CORPORATIONInventors: SOUMAYAJIT SARKAR, JAVED MAPKAR, JOHN TRUBLOWSKI, ADRI LAMMERS

Publication number: 20110212321Abstract: The present invention generally relates to a method for producing hybrid materials of thin polymer films with single, laminated, complete and/or partially embedded nanofibers to obtain products with unique functional properties. In one embodiment, the present relates to a hybrid process that utilizes both melt casting and electrospinning to produce nanofiber embedded functional films. In another embodiment, the process of the present invention involves nanofiber-containing products that are formed by producing a plurality of nanofibers via one or more nanofiber producing nozzles; depositing such nanofibers onto a melt cast polymer film; and either partially and/or completely embedding such nanofibers into the melt cast polymer film via one or more electrical forces.Type: ApplicationFiled: April 27, 2009Publication date: September 1, 2011Applicant: THE UNIVERSITY OF AKRONInventors: Miko Cakmak, Baris Yalcin, Soumayajit Sarkar
